Each Pega 7 Platform system has a production level, a value between 1 (lowest and least) and 5 (highest). This value affects many security features of your system.
The production levels are:
5 = production
4 = pre-production
3 = test
2 = development
1 = experimental
The System instance (the single instance of the Data-Admin-System class) contains the production level of your system. The current level is recorded as the value of the pzProductionLevel property on the Process page.
You can set this value during installation. You can change it anytime later.Production levels are referenced in Access of Role to Object rules and in various tools and wizards. In addition, through System Setting rules, you can assign distinct values for a setting based on the current production level.
To change the production level of a system, open and update the Production level field on the Production tab of the System data instance. The change takes effect (for a node) the next time that a node is started.
